Help I am freaking out. My DS1 just accidently pushed a trolley into someones BMW in the bunnings car park and put a tennis ball sized dent in the door. I did the right thing and waited for the guy to return to his car so I could get his details. He said he would get a quote to fix it and get back to me, so now i am freaking out. How much is this going to cost me, i cant claim it on my car insurance cause my car wasnt involved.
